Hi There! -First of all, this is not an AI-generated bid like most of the ones you're going to read, which I know can be very frustrating. -As you can see in my portfolio by visiting my profile, I have extensive experience in PCB development for automotive and industrial equipment, many of which use various versions of the ESP32. I can perfectly handle your PCB with the ESP32C5, integrating everything you mentioned, and adding a voltage monitor, which I consider essential in any ESP32-based device. We'll talk via messages for more details

@ElecHamza

Hi, I will design your ESP32-C5 baseboard following the DevKitC-1 reference while integrating the MCP23017 expander for your sixteen button interface. I will implement a robust power stage using a buck converter and MOSFET-based reverse polarity protection to safely handle the triple-input power system. The layout will feature strict RF keep-out zones, differential pair routing for USB, and dedicated power planes to support the high current demands of the WS2812 outputs. I will ensure the LIS3DH accelerometer and 74AHCT125 level shifters are placed optimally to prevent noise interference. You will receive production-ready Gerbers, a detailed bill of materials, and all assembly files for your activity controller platform. Best regards

Hi, this is a solid embedded board design job, and I can help turn it into something manufacturable and easy to bring up. I work on embedded systems with sensor interfaces, I2C devices, power separation, and hardware/software bring-up, so the mix here—ESP32, MCP23017 expansion, accelerometer, external connectors, USB flashing, and PCB layout constraints—fits well. On one embedded project, noisy power routing caused unstable sensor reads on a shared bus; I fixed it by cleaning up decoupling, placement, and return paths, which made bring-up reliable. I’d start from the ESP32 DevKitC reference, lock the schematic first, then place the power, USB, RF, and I2C sections before routing. The main risk is noise and boot/flash issues from mixed external IO and LED current, so I’d handle that early with layout isolation, strapping checks, protection, and test points. Thanks!

Hi there, I read your ESP32-C5 board specification carefully, and I can help design the complete plug-and-play activity controller PCB with the DevKitC-style core plus your extended buttons, WS2812 outputs, buzzer, accelerometer, and flexible power input system. The best approach is to first build the schematic around ESP32-C5-WROOM-1U and Espressif reference guidelines, then add protected power selection, MCP23017 button expansion, level-shifted WS2812 outputs, I2C accelerometer, buzzer driver, test points, and proper protection circuitry. After schematic validation, I would move to PCB layout with special care for RF keep-out, USB routing, LED power traces, grounding, and decoupling. I have solid experience with embedded hardware design, microcontroller boards, power circuitry, I2C peripherals, connector-based interfaces, and manufacturing-ready PCB files. What I will deliver: • Complete schematic • 2-layer/4-layer PCB layout • ESP32-C5 DevKit-style core circuit • Power input/protection design • MCP23017 button interface • WS2812 level-shifted outputs • Buzzer and accelerometer integration • BOM, Gerbers, and assembly files Cost: ₹10,000 || Timeline: 3 days Best regards Oluwatobi Okedairo

Hi, I can design a practical prototype version of this ESP32-C5 board within your budget. To keep things efficient and reliable, I would use the ESP32-C5-WROOM-1-N4 (integrated antenna), simplifying layout and avoiding RF complexity. I would implement this as a 4-layer PCB for clean power distribution, solid grounding, and easier routing of USB and mixed-signal sections. The design will include: * USB-C power and programming * Multi-input power (USB / barrel / terminal) * MCP23017 for button expansion * 3 WS2812 outputs with proper buffering * Buzzer driver * I2C accelerometer Deliverables: * Schematic (DipTrace) * 4-layer PCB layout * Gerbers + drill files * Pick-and-place / assembly files (JLC-ready) * Basic BOM At this budget, this is a prototype-ready design based on standard practices and reference implementations, without extensive optimisation or multiple revision cycles. Let me know expected LED load and any size constraints, and I can proceed. — Devin
